The original 16" alloy wheels are obviously fine for fair weather good pavement, but I'd like to have a different setup for slop and chuckholes. I'm pretty sure the 16" steel wheels from the SV/Sport will fit, but the brake calipers look like they have gobs of extra clearance and I'm wondering if there are any 15" steel wheels that will fit. Anyone have ideas? I think P185/70-15s would be awesome if they will fit.
